Contents
At present, setting the PYTHONPATH environment variable is the only method for defining additional Python module search directories.
This PEP introduces the '-P' valued option to the python command as an alternative to PYTHONPATH.
Rationale
On Unix:
python -P $SOMEVALUE
will be equivalent to:
env PYTHONPATH=$SOMEVALUE python
On Windows 2K:
python -P %SOMEVALUE%
will (almost) be equivalent to:
set __PYTHONPATH=%PYTHONPATH% && set PYTHONPATH=%SOMEVALUE%\ && python && set PYTHONPATH=%__PYTHONPATH%
Other Information
This option is equivalent to the 'java -classpath' option.
When to use this option
This option is intended to ease and make more robust the use of Python in test or build scripts, for instance.
